I got it!.......Micro stamping adds nothing more to serial numbers which already track buyers and owbers............Sheesh!
Actually, my post was more a reminder that serial numbers are useful for a lot of things, OTHER THAN "tracking buyers and owners". Long before the federal government started requiring SNs on firearms, a lot of manufacturers used them to track production, aid record keeping, and improve customer service. Although not mentioned in my previous post, serial numbers can also help a buyer or owner determine the legal status of a firearm (for example, whether it's a legal "antique" that may not require transfer through an FFL, or possibly a "curio & relic", which can be sold directly to most people with a C&R collector's FFL). I find firearm SNs very useful, and I don't "track" anyone...
